Add multiple Strings(words) into Array.

Question

I want to input 4 Strings and put them inside the array of food. After this the programm should randomly select a dish for me to eat.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main() {
srand(time(0));
vector <string> food;
std::string input;
std::string random;
do {
cin >> input;
food.push_back(input);
} while (food.size <= 4);
for (int i=0;i < 1; i++) {
random = food[rand() % 4];
cout << random << endl;
}
return 0;
}

This is the code but im not able to take multiple strings and store them inside one Array.

Are you using solo compiler? I mean did you try the code here? If it is, you should enter the food names one by one and after enter each one break a line, like:

Food1
Food2
Food3
Food4
Submit

Enter the food names as I wrote. Then submit. It works!

Answer 2

Ragnar Mxyzptlk ,

i think it should be:

...
while (food.size() <= 4);
...

Answer 3

You should define a variable to take input as much as 4 and increment it until 4 input taken.

So, try this. It works.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main() {
srand(time(0));
vector <string> food;
std::string input;
std::string random;
int k = 1;
do {
cin >> input;
food.push_back(input);
k++;
} while (k <= 4);
for (int i=0;i < 1; i++) {
random = food[rand() % 4];
cout << random << endl;
}
return 0;
}

Also, if you want to show to user that it must be enter a food each time, you add this line in the loop,

cout << "Enter the " << k << ". name of food" ;

Answer 5

Omg finally. It realy works!!! 🤣 Thank u very much! Crazy compiler...

Answer 6

With both the Compiler error is gone. But still if i run the programm i can just type in 1 word, it does not ask me 3 more Times to input a string. And i dont get it, im working 3 days just for this problem :D
